Expand description
Values that should be shared across all modules, without necessarily having to pass them all over the place, but aren’t consensus values. should be used sparingly.
Structs
Global acccept fee base that must be initialized once on node startup. This is accessed via get_acccept_fee_base() which allows the global value to be overridden on a per-thread basis (for testing).
Global chain_type that must be initialized once on node startup. This is accessed via get_chain_type() which allows the global value to be overridden on a per-thread basis (for testing).
Global future time limit that must be initialized once on node startup. This is accessed via get_future_time_limit() which allows the global value to be overridden on a per-thread basis (for testing).
Global feature flag for NRD kernel support. If enabled NRD kernels are treated as valid after HF3 (based on header version). If disabled NRD kernels are invalid regardless of header version or block height.
Enums
Types of chain a server can run with, dictates the genesis block and and mining parameters used.
Constants
minimum transaction fee per unit of transaction weight for mempool acceptance
Automated testing coinbase maturity
Testing cut through horizon in blocks
Automated testing edge_bits
Automated testing proof size
Mainnet|Testnet|UserTesting|AutomatedTesting
Trigger compaction check on average every day for all nodes. Randomized per node - roll the dice on every block to decide. Will compact the txhashset to remove pruned data. Will also remove old blocks and associated data from the database. For a node configured as “archival_mode = true” only the txhashset will be compacted.
Default unit of fee per tx weight, making each output cost about a Grincent
default Future Time Limit (FTL) of 5 minutes
maximum number of seconds into future for timestamp of block to be acceptable
Local feature flag for NRD kernel support.
Constant that expresses defunct peer timeout in seconds to be used in checks.
An enum collecting sets of parameters used throughout the code wherever mining is needed. This should allow for different sets of parameters for different purposes, e.g. CI, User testing, production values Define these here, as they should be developer-set, not really tweakable by users The default “local” protocol version for this node. We negotiate compatible versions with each peer via Hand/Shake. Note: We also use a specific (possible different) protocol version for both the backend database and MMR data files. This defines the p2p layer protocol version for this node.
If a peer’s last updated difficulty is 2 hours ago and its difficulty’s lower than ours, we’re sure this peer is a stuck node, and we will kick out such kind of stuck peers.
Testing initial block difficulty
Testing max_block_weight (artifically low, just enough to support a few txs).
Testing state sync threshold in blocks
Number of blocks to reuse a txhashset zip for (automated testing and user testing).
Number of blocks to reuse a txhashset zip for.
User testing coinbase maturity
Testing cut through horizon in blocks
User testing edge_bits
User testing proof size
Functions
Reference edge_bits used to compute factor on higher Cuck(at)oo graph sizes, while the min_edge_bits can be changed on a soft fork, changing base_edge_bits is a hard fork.
Coinbase maturity for coinbases to be spent
Return either a cuckaroo* context or a cuckatoo context Single change point
Horizon at which we can cut-through and do full local pruning
Converts an iterator of block difficulty data to more a more manageable vector and pads if needed (which will) only be needed for the first few blocks after genesis
Accept Fee Base Look at thread local config first. If not set fallback to global config. Default to grin-cent/20 if global config unset.
Get the chain type via thread_local, fallback to global chain_type.
Future Time Limit (FTL) Look at thread local config first. If not set fallback to global config. Default to false if global config unset.
Calculates the size of a header (in bytes) given a number of edge bits in the PoW
One time initialization of the global accept fee base Will panic if we attempt to re-initialize this (via OneTime).
One time initialization of the global chain_type. Will panic if we attempt to re-initialize this (via OneTime).
One time initialization of the global future time limit Will panic if we attempt to re-initialize this (via OneTime).
One time initialization of the global NRD feature flag. Will panic if we attempt to re-initialize this (via OneTime).
Initial mining difficulty
Initial mining secondary scale
Is the NRD feature flag enabled? Look at thread local config first. If not set fallback to global config. Default to false if global config unset.
Are we in production mode? Production defined as a live public network, testnet[n] or mainnet.
Are we in testnet? Note: We do not have a corresponding is_mainnet() as we want any tests to be as close as possible to “mainnet” configuration as possible. We want to avoid missing any mainnet only code paths.
Maximum allowed block weight.
Maximum allowed transaction weight (1 weight unit ~= 32 bytes)
The minimum acceptable edge_bits
Minimum valid graph weight post HF4
